Patented May 4, 1909.

Application filed December 7, 1906. Serial No. 346,786,

To all whom it may concern Be it known that I, PHILIP J. DALTON, a citizen of the United States, residing at Joliet, in the county of Will and State of Illinois, have invented certain new and useful Improvements in Rail-Joints, of which the folowing is a specification.

This invention relates to rail joints, and has in view the provision of a practical and effective joint embodying in its construction a firm and substantial metal base support for the rails. v 7

To this end the invention contemplates a rail joint of the base supporting type wherein the various elements of the oint are interlocked and held against relative displacement,

nature of the invention is better understood,

the same consists in the novel construction and arrangement of parts hereinafter more fully described, illustrated, and claimed.

The essentialfeatures of the invention are necessarily susceptible to modification without departing from the scope of the invention, but a preferred embodiment thereof is shown in the accompanying drawings, in which: 7

Figure 1 is a side elevation of a form 0 rail joint embodying the invention. Fig. 2 is a sectional perspective view on the line 66 of Fig. 1. Fig. 3 is a detail perspective view of a section of the'form of base plate embodied in the joint shown in Figs. 1 and 2. Fig. 4 is a sectional perspective viewofa modification embodying the invention. Fig. 5 is a detail in perspective of the modified form of base plate employed in the construction shown in Fig. 4 ofthe drawings.

Like references designate corresponding parts in the several figures of the drawings.

The improvements contemplated by this invention are susceptible to embodiment in different forms of joints, but in all adaptations the same essential features are preserved. However, the construction claimed is well exemplified by the form of rail joint shown in Figs. 1, 2, and 3 of the drawings, and referring first to this construction,.it will be observed that the joint illustrated in said figures includes in its general organization the adjac'entfservice'or running rails 1 and 2, the opposite side angle bars 3, the joint bolts 4; having the usual nuts 6, and a main metal base plate 7 having a separable interlocking engagement with both angle bars, as will presently appear. The side angle bars 3 are of duplicate design and construction, and each of the same is provided witha main splice bar portion having the usual bolt holes for the reception of the joint bolts i, and with a foot flange 9 overlying the base flange of the rails, as plainly shown in Figsjl and 2 of the drawings. A distinctive feature of the resent invention resides in so constructing t e foot flanges 9 of the angle bars that the same are formed with what may be characterized as shouldered base fastening sections which have a separable interlocking engagement with upstanding girder flanges arising from the base plate 7 and preferably forming an integral part of edge portion 27 of the foot flange 9 of each angle bar with a plurality of alternated re versely disposed holding shoulders 28 which interlock with the complemental matching correspondingly arranged retaining shoulders 29 formed on and along the up er edge of the sidegirder flanges 10 of the ase plate 7 This form of base plate 7" is illustrated as having a plain body portion, and in addition to having the series ofreversely disposed and alternated shoulders 29, said base plate 7 a is formed at opposite side edges thereof, and intermediate 1ts ends, with the pendent stiffening girders or flanges'30 which serve to stiffen and reinforce the base plate in the vertical plane of the joint between the meeting ends of the rails v In the form of joint shown in Figs. 4 and 5 of the drawings the'foot'flan'ges 9 of the angle bars are illustrated as being rovided at their outer edges with pendent ange extensions 31 in which are formed long keeper notches 11 within which register plain, comparativelylow, girder flanges 10 arising from opposite portions ofthe body of the base plate 7 These girder flanges 10 are illustrated as terminating Within the plane of the keeper notches 11 of the angle bars, and the body ortion of the base plate may terminate with t 1e flanges 10 or may be continued out to the ends of the joint, to afford a full-length base support. In addition to the girder flangeslO the modified form of plate 7 is preferably constructed with the side spiking flanges 32 arranged outside of the vertical plane of the flanges 10 and )rovided between the ends of the plate bo iy with pendent stiffening flanges or girders 33. I

Various other modifications will suggest themselves to those skilled in theart, and it Will therefore be understood that changes in the form, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

I claim:

1. In a'rail joint, the rails, side angle bars, each of which is provided at the outer edge of its foot flange with a pendent shouldered flange portion, and a separate base-plate underlying the rail ends and provided with upstanding girder flanges lying within the vertical planes of the flange portions of the opposite angle bars and presenting a plurality of shoulders interlocking with the shoulders of said flange portions.

2. In a rail joint, the rails, side angle bars, each of which is provided at the outer edge of its foot flange with a pendent shouldered flange portion having a series of shoulders, and a separate base-plate provided at its side edges With upstanding girder flanges also having a series of shoulders arranged in matching and opposing relation to those of said flange portions of the angle bars.

In testimony whereof I hereunto aflix my signature in the )resence of two witnesses.

PI ILIP JOIIN DALTON.
